Embodiment 1

[0035] First prepare chicken manure fermented fertilizer, prepare 55 tons of chicken manure, 20 tons of bran powder, 19 tons of flue-cured tobacco straw, 1 ton of EM raw dew, 1 ton of basalt powder, and 4 tons of tea shell powder, of which EM raw dew is from Tianyi Biotechnology of Jiangxi Province The products produced by the company are developed; then the chicken manure is crushed, deodorized, dried, and then the flue-cured tobacco stalks are crushed; then the chicken manure, bran powder and 600kgEM original dew are fully stirred evenly, and then stacked for 30 days of anaerobic fermentation. During the period, turn the compost once every 3 days, keep the fermentation temperature not lower than 35°C and not higher than 65°C, turn the compost on the last day to let the temperature drop; when the temperature drops to 20-30°C, add 400kg of EM raw dew and crushed flue-cured tobacco Stir the stalks well, and then ferment them again for 7 days. During this period, turn them over o...

Embodiment 2

[0044] First produce 60 tons of chicken manure fermented fertilizer according to embodiment 1.

[0045] Then prepare 26 tons of urea, 7 tons of monoammonium phosphate, 7 tons of potassium sulfate, 60 tons of chicken manure fermented fertilizer, 8 tons of wood carbon powder, 2 tons of superphosphate, 1 ton of bentonite, and 1 ton of solid bacterial agent. It is nitrogen-fixing bacteria, rhizobia, phosphorus-releasing bacteria, potassium-solving bacteria, bacillus and actinomycetes, and the bacteria content per gram is more than 2 billion.

[0046] First, each raw material is pulverized with a pulverizer; then urea, monoammonium phosphate, potassium sulfate and wood charcoal powder are added to the mixture, mixed and stirred evenly, and then sent to a drum granulator for rolling granulation; and then the particles are screened , take granules with a particle size of 1.5-2.5mm, and return the rest to re-grind and granulate; then fully mix 0.72 tons of superphosphate and 0.32 tons...

Embodiment 3

[0053] First produce 60 tons of chicken manure fermented fertilizer according to embodiment 1.

[0054] Then prepare 14 tons of urea, 4 tons of monoammonium phosphate, 4 tons of potassium sulfate, 32.5 tons of chicken manure fermented fertilizer, 4.5 tons of wood charcoal powder, 1.1 tons of superphosphate, 0.6 tons of bentonite, and 0.5 tons of solid bacterial agent. It is nitrogen-fixing bacteria, rhizobia, phosphorus-releasing bacteria, potassium-solving bacteria, bacillus and actinomycetes, and the bacteria content per gram is more than 2 billion.

[0055] First, each raw material is pulverized with a pulverizer; then urea, monoammonium phosphate, potassium sulfate and wood charcoal powder are added to the mixture, mixed and stirred evenly, and then sent to a drum granulator for rolling granulation; and then the particles are screened , take the particles with a particle size of 2mm, and return the rest to re-grind and granulate; then fully mix 0.8 tons of superphosphate a...

Abstract

The invention provides a complex control type long-acting controlled-release organic and inorganic biological fertilizer and belongs to the technical field of fertilizers. A raw material formula comprises 24-28 parts of urea, 6-8 parts of monoammonium phosphate, 6-8 parts of potassium sulfate, 55-65 parts of chicken manure fermented fertilizer, 7-9 parts of wood charcoal powder, 1.8-2.2 parts of calcium superphosphate, 0.8-1.2 parts of bentonite and 1 part of solid inoculant. The complex control type long-acting controlled-release organic and inorganic biological fertilizer has the beneficial effects that firstly, a nitrogen phosphorus and potassium fertilizer and the wood charcoal powder are mixed and granulated; the wood charcoal powder has the adsorption function so that fertilizer nutrients can be slowly released; the outer surfaces of initial grains are covered by a mixture of the calcium superphosphate and the bentonite to control the releasing of the nutrients; the chicken manure fermented fertilizer is used for covering the grains and then the solid inoculant is sprayed; the inoculant can control the releasing of nitrogen, phosphorus and potassium; and then the outer surface of the inoculant is covered by the mixture of one layer of the calcium superphosphate and the bentonite, so that the complex control type long-acting controlled-release organic and inorganic biological fertilizer is formed through a plurality of times of slow release and controlled release.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a complex-controlled long-acting slow-release organic-inorganic biological fertilizer which adopts coating controlled release, adsorption slow-release and biological slow-release to achieve comprehensive slow-release effects. Background technique [0002] my country is a large agricultural country, and fertilizer plays a very important role in my country's grain production, and is the largest material investment among farmers' productive investment. However, due to the limitation of fertilizer production and use technology, the nutrients in the fertilizer have not been effectively utilized, resulting in a decline in soil fertility, a decrease in fertilizer utilization rate, and damage to the ecological environment. At present, the level of scientific production and fertilization in my country is not high as a whole, and there is still the phenomenon of blind fertilization in some areas. The waste ...
